The ad declared the Republican nominee to be dangerous and unfit to be president by showing small parts of a speech he made last year, saying "I love war" and expressing admiration for the power and devastation of nuclear war.

Conway, appearing on ABC's Good Morning America on Wednesday, criticized the 30-second ad for "cherry-picking little snippets of what he said and not giving the full context of the sentence let alone the speech."

When asked what exactly Trump meant by the sentences the ad shows him uttering, Conway said "I'd have to see the entire snippet there," and then quickly went into criticism of Clinton's record as secretary of state for four years, when she was "actually in control of many aspects of our national security."

"You have Hillary Clinton as secretary of state calling a Russia reset that didn't work, she was wrong on Libya, she was wrong on Syria, she was certainly wrong on Benghazi," Conway said.

Trump's campaign manager also said it was important not just to do ads against each other, "because people deserve a conversation with the candidates," emphasizing that Trump does very few ads and is out on the campaign trail all the time talking to the voters directly.

Conway gave as an example the 88 senior retired military officials who wrote an open letter of support for Trump in The New York Times on Tuesday in which they said a "long overdue course correction in our national security posture and policy" is necessary and "can only be made by someone who has not been deeply involved with, and substantially responsible for, the hollowing out of our military and the burgeoning threats facing our country around the world."

Conway emphasized to ABC that Trump also did in the past few days "a military preparedness town hall in Virginia, then he was in North Carolina and he got to talk to the voters directly."
